My invention relates to pressing machines and more particularly to headelements and buck elements employed therein.

' The principal object of the invention is to provide either a headelement or a buck element. or both. capable of simultaneously ironingthe top and sides or sleeves and the like. To carry out this object, itis the further object of my invention to provide ilexibility in one orboth of said elements, which will permit such element or elements toilex upon engagement with each other and exert pressure against thesides as well as the top of the garment being pressed.

Another object of my invention is to provide means for holding an end ofthe garment while adjacent portionsare being ironed. Still anotherobject is to provide means to prevent such ilexible elements frompinching or leaving a crease upon a garment.

My invention also has for its object to provide such means and elementsthat -are positive in operation, convenient in use, easily installed ina working position and easily disconnected therefrom, economical ofmanufacture, relatively simple and of general superiority andserviceability.

The invention also comprises novel details of ,construction and novelcombinations and arrangements oi parts, which will more fully appear inthe course of the following description. However, the drawings merelyshow and the following description merely describes one embodiment ofthe present invention, which is given by way of illustration or exampleonly.

Figure 14 is a perspective view of a head comprised in said modiiiedconstruction.

Figure 15 is a perspective view of a buck comprised in said modifiedconstruction.

Referring more in detail to the drawings, the reference number I2, inFigure l, generally designates a frame of a pressing machine having abuck I 3 supported by a goose-neck 9 I. The end of the buck I3 is ofreduced size, as shown at I4. The buck carries padding I5.

A pressing arm IS on the pressing machine carries a cross plate I1. Thepressing head includes two members I8 and I9 provided with hingeknuckles 29 and 2I on member I9, and hinge knuckle 22 on member I 8.Suitable hinge pins 23 are inserted in the knuckles 20 and 22 toarticulate the head members I8 and I9. Steam chests 24 and 25 arerespectively mounted on the` outer surfaces of the head members I8 andI9.

Bolts 26 and 21 engage nuts 28 and 29, mounted on the member I9 at thetop of the wedge-shaped head 39, which head comprises the members I8 andI9. Springs 3i and 32, respectively coiled around the bolts 26 and 21,urge the nuts 28 and 29, and thereby the head 30, downwardly. Thus whenthe plate I1 is moved downward by the arm I6, the said plate compressesthe springs 3i and 32.

Mounted upon the sloping downwardly extending sides of the head membersI8 and I9 are upstanding bosses 33 and 34 which are interiorly threaded.Bolts 35 and 36 are disposed loosely in openings 31 and 38 in the plateI1. When the plate I1 is moved down to a pressing position, it not onlycompresses the springs 3i and 32, but also bears against the tops of thebosses 33 and 34, thus causing the head members I8 and I9 to swinginwardly toward each other, thus simultaneously pressing the top andsides of any material on the buck I3.

A steam inlet is provided at 39 and a steam outlet at 4D. Similar inletand outlet are provided for the steam chests 24 and 25. A flexibletubing 4I connects the inlets of the steam chests 24 and y 25 with eachother and a exible tubing 98 conjoin, at the ends thereof, and arefastened by nuts |84 on the hinge pins 23. The strip 83 does notinterfere with the pressing operation but does prevent creasing andpinching of the buck or material being pressed.

In the modified construction shown in Figure 10, the iiexible connectingtubing 43 is shown as looped at 44 to increase its flexibility. Aholding means is provided for holding the end of the sleeve whileadjacent portions oi the sleeve are being pressed. This means comprisesside plates 45 and 46 hinged to each other at 41. Pads 48 and 49 areprovided on the inside oi the plates 45 and 46 respectively, to grip anend of a sleeve on the buck end I4.

Means for pressing the members 45 and 46 toward each other include links50 and 5| which are respectively pivoted to arms 52 and 53 .on the sideplate members 45 and 46. A shaft 54 is carried by an operating arm 55.The shaft is keyed to the arm 55 and to an abutting linger 56, as shownat 51. The finger 56 has a tip 58 that extends under link 50 to preventthe links 50i and from reaching dead-center. A lug 59 on the arm 55similarly limits link 5I. f

The arm 55 is pivoted at 60 on the frame I2 of the machine. A connectingrod 6| actuates lever arm 55. A pedal 62, pivoted at 63, operativelyconnects with the connecting rod 6|. Thus the holding means 45 and 46may be moved to a buck-engaging position to hold the garment in placeprior to the descent of the head `to a. pressing position.

In the modication shown in Figures 'I and 8, sideplates 64 and 65 carryon their inner faces pads 66 and 61 respectively. for engaging thepadded sides 68 of the buck I4. The side plates 64 and 65 are pivoted toeach other at 69. Arms and 1I on the side plates 64 and 65, are urgedtogether by a coil spring 12 which hooks around the arms 10 and 1I, asshown in Figure 8. A stiiening rod 13 maintains the spring 12 inalignment. The rod 13 reciprocates in recesses 14 and in the arms 10 and1I respectively. v

Actuating means for the holding device shown in Figures '1 and 8,includes a lever arm 16 pivotally mounted at 11 and connected to bolts18 and 19 on the arms 10 and 1|. Slots 80 and 8| in the lever 16 permitsthe bolts 18 and 19 to move toward and away from each other laterallyduring movement of the arms 10 and 1I toward and away from each other.

The lever 16 is operated by a connecting rod 82 in the same manner asthe connecting rod 6I and associated parts actuate the lever arm` 55.

In the form shown on Sheet 111.01 the drawings, the head 85 has a fixedcross-sectional shape. A steam chest 86 is provideddfor heating the head85. Inlet and outlet connections 81 and 88 are provided for the steamchest 86. Arm 89 on the pressing machine, similar to arm/I6, supportsthe head 85.

The buck, in this form, is the ilexible member. A wedge-shaped coremember 90 o! the buck extends laterally from a goose-neck 9|. Recesses92 in the buck member 90 carry helical springs 93. which in turn supporta ridge member 94. Side members 95 and 96 of the flexible buck re- 5spectively, have alternating fingers 91 and |01 that hook over the ridgemember 94I whereby the side members 95 and 96 may swing towards and awayfrom each other. Steam chests 99 and |00 are disposed on the inner facesof the side l0 members'. Inlets |0| and |02 are provided for the steamchests 99 and |00. Suitable outlets (not shown) are also provided.

Padding |09 extends over the buck members 95 and 96 from edge to edge ofthe buck. A fac- 15 ing material |04 is in turn applied to the padding.The material |04 may also be continuous across the bottom of the buck,to cover same.

However, there should be a looseness in the portion of the material |04that is under the buck,

2o to permit expansion of the sides of the buck.

In the operation of my device, actuating means for the arm I6 may be anysuitable motive means. The actuating means per se forms no part of thepresent invention.

The arm I6, when lowered, carries the wedgeshaped head down into contactwith the padding I5 on the buck. The springs 3| and 32 resiliently urgethe head 30 against the top surface of the buck. Further downwardmovement 30 of the plate |1 causes it to bear against the upper surfaceof the bosses 33 and 34, which, because oi their position, thereby causethe head members I6 and I9 to swing inwardly toward the buck.

This eects pressing of the material at the sides of the buck. Theintroduction of steam through the inlet connection 39, and the dischargeof condensate through the outlet connection heats the head members.-Conduits 4I and 98 connect the steam chests of the head members 40 witheach other, whereby steam is introduced to steam chest 24 through theconduit 4| and condensate is discharged from that steam chest throughthe conduit 98.

The holding means comprising the side plates a portion of the garmentsuch as a cuff on the reduced end I4 of the buck. The remainder of thegarment, such as the sleeve, may then be drawn over the buck, to theleft in Figure 1, to eliminate wrinkles. Thereupon the member 30 islowered into the pressing position as described.

Cushions 46 and 49 (or 66 and 61) engage and rmly hold the portion ofthe garment contacted by same. 'I'hereupon the lever 55, through theintermediary of the links 50 and 5|, cause the plate members and 46 tomove inwardly toward buck I4.

In the form shown in Figures '1 and 8, the vlever 16 presses downward onthe arms 10 and 1|, thus causing the side plates 64 and 65 to grip thebuck. When the lever 16 is raised the spring 12 draws the side plates 64and 65 away from the buck. Springs 84 tend to maintain the lever 16 andthe ends of the arms 10 and 1I in contact with each other.

In the operation of the form shown in Sheet III, the side members 95 and96, which are arranged in a wedge-shape, vrest upon the sides of thewedge-shaped buck 90. The garment to be pressed is placed on thematerial |04 and the head 85 is caused to descend. As the head 85 movesdownward, after contact with" the garment. the side members 95 and 96ride down- 75 ward on the outward flaring, wedge-shaped mem- 45 and 46(or 64 and 65) is rst lowered to hold.

ber 90, thus swinging the side members outward around the axis of theridge member 94.

In the forms shown in both Sheet I and Sheet III, the flexible membernrst contacts the other pressing member, substantially at the flexingaxis thus pressing the portion of the article on top of the buck, and`then by further pressing invention, the construction is, of course,subject to modifications without departing from the spirit and scope ofmy invention. I, therefore, do not Wish to restrict myself totheparticular form of construction illustrated and described, but desire toavail myself of all modiiications that may fall within the scope of theappended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:
